POST /fine-tunes/estimate-price returns estimated fine-tuning job cost before launch

A new endpoint, POST /fine-tunes/estimate-price, returns the estimated total price of a fine-tuning job before you launch it, along with estimated training and evaluation token counts and your remaining credit limit. Call it from the Python SDK or TypeScript SDK with the same parameters you plan to submit to the create-job endpoint.

See Fine-tuning pricing for details.
